Release Notes: There have been no new features since 10/31, this release is just recompiled to support "older" 1.6 JRE users, as the author had accidentally set the IDE to 1.7.

Release Notes: 65c02 CPU emulation is now 100% and verified. CPU usage is greatly reduced. Games detect mockingboard now: SkyFox and Pitfall II. A Disk II speedup hack option was added.

Release Notes: Mockingboard now sounds perfect with Ultima 5. Fullscreen support (press F9 to toggle) has been added. New graphical indicators have been added for ram, disk, serial, and mouse activity.

Release Notes: This release re-architects the underlying memory event handler model to include CPU opcode/operand memory accesses. A new memory heatmap view has been added to metacheat (press END to activate); this lets you see active reads/writes/executes in memory as they happen. It fixes graphics glitches in hi-res mode. It improves RGB Mode 7 support to auto-detect RGB mode. It fixes a Disk ][ bug that caused hangups in programs like Apple Desktop ][. This is a very stable release.
